MacConkey Agar No.2 is a modification of MacConkey Agar which contains bile salts No. 2 for the recognition of Enterococci.
This agar especially useful when looking for Enterococci in the presence of coliforms and non-lactose fermenters from water, sewage and food products. Enterococci are frequently sought as an index of fecal pollution and appear on this medium as small, intensely colored red-purple colonies. Non-lactose fermenters appear colorless, whilst bile tolerant Gram-positive organisms, such as staphylococci and non-fecal streptococci, are completely inhibited.
